For many years, Sudan had an Islamist regime under the leadership of Hassan al-Turabi. His National Islamic Front first gained influence when strongman General Gaafar al-Nimeiry invited members to serve in his government in 1979. Turabi built a powerful economic base with money from foreign Islamist banking systems, especially those linked with Saudi Arabia. He also recruited and built a cadre of influential loyalists by placing sympathetic students in the university and military academy while serving as minister of education.
